The aim of the study was to perform treatment of juniper wood to obtain wood material with a density and mechanical properties comparable to bone, thus producing a potential material for use in osteosynthesis bone implants. In the first step, partial delignification of wood sample was obtained by Kraft cooking. The second step was extraction with ethanol, ethanol–water mixture, saline, and water to prevent the release of soluble compounds and increase biocompatibility. In the last step, the thermal densification at 100 °C for 24 h was implemented. The results obtained in the dry state are equivalent to the properties of bone. The swelling of chemically pre-treated densified wood was reduced compared to chemically untreated densified wood. Samples showed no cytotoxicity by in vitro cell assays. The results of the study showed that it is possible to obtain noncytotoxic wood samples with mechanical properties equivalent to bones by partial delignification, extraction, and densification. However, further research is needed to ensure the material's shape stability, water resistance, and reduced swelling. [ABSTRACT FROM AUTHOR]

Craniofacial development is a critical aspect of pediatric growth, influencing fields such as physical anthropology, pediatrics, forensic sciences, and clinical practice. Objectives: This study aimed to assess the trends in craniofacial measurements and indices in Latvian children aged 1–15. Methods: The anthropometrical measurements (head circumference, length, width, facial length, and width) were conducted on 375 children according to the guidelines by R. Martin, K. Saller, and J. Prīmanis at the Anthropology laboratory at the Institute of Anatomy and Anthropology, Rīga Stradiņš University. The cephalic index (CI) and the facial or prosopic index (PI) were calculated, allowing for a detailed examination of cranial and facial proportions. The data were analyzed using descriptive and inferential statistics, including the Pearson Chi-square test and the Spearman correlation coefficient. Results: The findings revealed a consistent increase in head circumference with age, with boys generally having slightly larger heads than girls. The boys and girls exhibited growth in head length and width, particularly noticeable between 1 and 2 years of age. Facial length and width increased with age, with boys typically having longer facial lengths and broader faces than girls. The most common cephalic index category is mesocephaly, which accounts for 52.85% of the population, followed by dolichocephaly at 32.94%. Brachycephaly and hyperbrachycephaly are less prevalent, representing 11.36% and 2.86% of the population. Regarding the facial index categories, hypereuryprosopic is the most prevalent, representing 45.54% of the population, closely followed by euryprosopic at 43.74%. Mesoprosopic is significantly less common, representing only 9.95%. The least common categories are leptoprosopic and hyperleptoprosopic, with prevalences of 0.64% and 0.12%, respectively. The indices analysis showed variations across age groups, with dolichocephaly being more common at younger ages and decreasing over time. Brachycephaly and hyperbrachycephaly remained relatively stable or decreased slightly with age, while mesocephaly displayed less variation. The relationship between the FI and CI in younger age groups was typically weak to moderate and inverse, with a significance level of p < 0.001 or p < 0.01. However, no meaningful correlation was observed in older children aged 14–15. Conclusions: This study provides valuable insights into the craniofacial development of Latvian children, highlighting the measurements, cranial and facial types, and their variations across age groups.

This study provides a comprehensive analysis of the physical development patterns from birth to adolescence, utilizing a longitudinal dataset of 70 children monitored from birth until 17 years of age. The research focuses on the variability of growth trajectories, emphasizing the role of genetic and environmental factors in influencing these patterns. Key findings indicate that most children undergo one or two periods of accelerated growth, with significant variability in the timing and magnitude of these growth spurts. The study also highlights the adaptive nature of growth changes over generations, influenced by ecological, nutritional, and socio-economic conditions. The longitudinal approach reveals critical insights into the timing of peak growth velocities, demonstrating that girls reach their growth peak approximately one year earlier than boys. The analysis of intergenerational growth patterns suggests a significant increase in average height over the century, attributed to genetic diversity and changes in lifestyle and nutrition. This study's findings emphasize the importance of updating physical development standards regularly to reflect the changing genetic and environmental landscape. The variability in growth patterns and their correlation with health outcomes in later life highlights the need for targeted public health strategies that address the underlying socio-economic and environmental determinants of health. This research contributes to the understanding of physical development trajectories and provides a foundation for future studies aimed at optimizing health outcomes from early childhood through adolescence. The primary objective of this article is to meticulously analyze the dynamics of height growth and accurately identify the periods of accelerated bodily development within the context of longitudinal research.

Remotely sensed flood extents obtained in near real-time can be used for emergency flood incident management and as observations for assimilation into flood forecasting models. High-resolution synthetic aperture radar (SAR) sensors have the potential to detect flood extents in urban areas through clouds during both day- and night-time. This paper considers a method for detecting flooding in urban areas by merging near real-time SAR flood extents with model-derived flood hazard maps. This allows a two-way symbiosis, whereby currently available SAR urban flood extent improves future model flood predictions, while flood hazard maps obtained after the SAR overpasses improve the SAR estimate of urban flood extents. The method estimates urban flooding using SAR backscatter only in rural areas adjacent to urban ones. It was compared to an existing method using SAR returns in both rural and urban areas. The method using SAR solely in rural areas gave an average flood detection accuracy of 94% and a false positive rate of 9% in the urban areas and was more accurate than the existing method.

Wearable technologies provide many possibilities for applications in medicine, and especially in physiotherapy, where tracking and evaluation of body motion are of utmost importance. Despite the existence of multiple smart garments produced for applications in physiotherapy, there is limited information available on the actual impact of these technologies on the clinical outcomes. The objective of this paper is to evaluate the impact of the Double Aid (DAid) smart shirt, a purely textile-based system, on the training process of patients with subacromial pain syndrome. A randomized controlled trial was performed where patients with subacromial pain syndrome had to perform the assigned training exercises while employing the DAid smart shirt system. The core point of each exercise was to perform a movement while holding the shoulders stationary. The smart shirt was designed to sense even slight shoulder motion thus providing the patient with feedback on the accuracy of the motion, and allowing the patient to adjust the movement. The appropriate muscles should be strengthened through an increased effort to control the shoulder motion. The recovery of patients using the feedback system at the end of the treatment was compared to that of a reference group through standardized tests—the Disabilities of the Arm, Shoulder, and Hand score (DASH score), Closed Kinetic Chain Upper Extremity Stability test (CKCUES test), and internal/external rotation ratio. The test group that used the DAid system demonstrated significantly better results of the performed tests for all applied outcome measures compared to the reference group (p < 0.001). An overall positive impact on the patient recovery was observed from the DAid smart shirt system when applied for rehabilitation training of patients with subacromial pain syndrome.

In order to provide targeted support to families who are raising children with developmental disorders, it is important to study the family needs and to understand circumstances that may affect them. The aim of this study was to identify the needs of the families with preschool children with cerebral palsy, and study how these needs relate to factors associated with families, children and rehabilitation services. Descriptive analysis showed that families living in Latvia most often need information, social and financial support and coordination of services, and they also need financial support to cover the costs of child care and treatment. The results of the data analysis support the hypothesis that factors characterising families, children with cerebral palsy and rehabilitation services affect the needs of the families with preschool children with cerebral palsy living in Latvia, and the unique impact of these factors depends on the type of needs. Regression analysis revealed that the most important factors affecting the needs of families were related with the socio-economic situation, as well as the support of peers and professionals. The availability and regularity of rehabilitation services, limitations to the child's functions and health impairments were factors that affected family needs to a lesser extent.

Background and Objective: An understanding of the needs of families of preschool children with cerebral palsy (CP) is of essential importance if efficient and cost-effective services are to be provided to them. The aims of this study were to identify the most frequently expressed needs of families with preschool children with CP; differences in the amount and types of family needs based on the child's gross motor function and communication function level; and the impact of the child's gross motor function and communication function level on the type and amount of family needs., Materials and Methods: A total of 227 parents of preschool children with CP completed a modified version of the Family Needs Survey and a demographic questionnaire. Children's gross motor function level and communication function level was classified using the Gross Motor Function Classification System (GMFCS) and the Communication Function Classification System (CFCS), respectively., Results: The total number of family needs differed based on GMFCS and CFCS levels. Children's GMFCS and CFCS level were not significant predictors of overall family needs (adjusted R(2)=0.163). In this model the GMFCS level of children did not account for the total number of family needs, while the CFCS level did., Conclusions: Child's limitations in terms of communication and gross motor functions must be taken into consideration when planning services for families with preschool children with CP., (Copyright © 2014 Lithuanian University of Health Sciences.
